| 摘 要： | 基于1∶5万土壤和灌溉水地球化学调查结果,对河北枣强开展了土地质量地球化学评估。结果显示评估区土壤养分相对缺乏,尤以全氮、有机质、有效钼、硫缺乏最为严重;大部分面积的土壤环境质量为一级清洁区,占评估区总面积的99.66%;灌溉水水质良好,重金属全部符合农田灌溉水质标准,部分区域氟化物和p H值超标。

| Abstract: | Based on geochemical survey of soil and irrigation water at 1∶ 50000 scale，the land quality in Zaoqiang was evaluated by the method of geochemical assessment． The results show that the soil nutrient is rela- tively insufficient，especially N，Org． C，available Mo and S． The environmental quality of soil in most studied area was clean，which accounts for 99. 66% of the total assessment area． The quality of the irrigation water is good． The heavy metal content in irrigation water was in the range of the standards for irrigation water quality，but fluoride and pH in some sampling points exceed the standards． |
